Considering the gap between academic research and real world application, the characteristic of manufactories of "much variety and little batch", this paper discusses the abstraction and modeling of the workshop performance using colored Petri net characterizing definite description of DEDS. And rule bases are applied into the model to tackle the dynamic events and disturbances with dynamic scheduling. After analysis on agile response of MES and integration of its scheduling model, by adopting distributed component technology the workshop scheduling model was capsulated as a scheduler to realize the scheduling module of MES easier to be integrated and rapidly reused. Finally a prototype of scheduler is proposed.

鉴于最优调度理论与实际调度应用的距离，以及多品种单件小批量车间生产的特点，本文以某模具制造企业生产车间为研究对象，利用对离散动态系统具有准确描述能力的着色 Petri 网对车间生产进行了抽象和建模；并通过向网系统中引入规则约束，为车间内的动态事件和扰动提供了动态调度；在对 MES的敏捷性及其车间调度模块的集成性进行了多方面分析后，利用分布式组件技术将调度模型进行了软件封装，以便为 MES 提供一个功能独立、易集成、可快速重用的生产调度模块；最后给出了一个 MES 车间调度服务器和调度室客户程序的原型实现。

Risk and maneuverability analysis on engineering design is widely used to conduct security appraisal abroad. The potential risks might be caused by technical parameter deviation, failure and faulty operation of facilities and pipelines in the system were normally analyzed along with the reason why deviation and faulty operation occurred. The acceptable risk was then appraised according to the results, reasons and designed protective facilities. Later, the security countermeasures and solutions were brought forward purposively to further modify and refurbish the security design and operation management.
